Referring to the first to third figures, the electrical connector assembly 1 includes an electrical connector 100 and a circuit board 200. The electrical connector 100 includes an insulative housing 110 and a complex assembled to the insulative housing 110. Number of conductive terminals 120.

The insulative housing 110 includes a base portion 111 and abutting portion 112. A pair of guiding portions 113 are disposed on both sides of the abutting portion 112, and the guiding portion 113 is formed to extend from the front end surface 1111 of the base portion 111. The base portion 111 has a longitudinal shape and has opposite front end faces 1111 and rear end faces 1112. The abutting portion 112 includes a pair of tongue plates 1120 of different lengths and L shapes. The pair of tongue plates 1120 extend from the front end face 1111 and Each of the pair of receiving spaces 1113 has a partition wall 1113. The rear end surface 1112 of the base portion 111 is recessed toward the front end surface 1111 to receive a pair of receiving spaces 1113 corresponding to the tongue plate 1120. 1119 separated.

Referring to the third and fourth figures, the conductive terminal 120 has a holding portion 121 fixed to the base portion 111, a contact portion 122 extending from the front end of the holding portion 121, and a tail portion 123 extending from the rear end of the holding portion 121. The contact portion is formed. The contact surface 1121 of each of the tongue plates 1120 is in contact with a mating terminal (not shown). The tail portion 123 of the conductive terminal 120 includes a curved portion 1231 protruding from the rear end surface 1112 and a distal end surface 1111 from the end of the curved portion 1231 toward the base portion 111. The welded portion 1232 is formed to extend in the direction, and the curved portion 1231 is U-shaped or C-shaped, and the welded portion 1232 is located at the top surface 1116 of the receiving space 1113. The receiving space 1113 includes a plurality of recesses 1115 recessed from the top surface 1116 thereof.
